Type 71 Arctic littoral combat ship
1) The ship must be armed with a minimum of A main cannon (literally any caliber will do) and at the least one or two Heavy Machine Guns. Yes 1x 155mm and 2x 30mm, also has decoy launchers, ASW TT and multiple VLS silos for a full range of missiles
2) Minimum icebreaking levels. By the Polar Classification system it would be PC 3 (although PC 2 designs will be given great praise, and PC 1 designs will be godly) Unsure ICE3 or PC1 designed for Polar and Antarctic missions certainly not hindered by thick ice?
3) Role requirements. This challenge is targeted towards surface ships only, and excludes submarines. Definitely not under the water
Thats it! Have fun!
